Selena Gomez and Charlie Puth Just Previewed Their Duet on Instagram

Talk about not wasting time! Selena Gomez and Charlie Puth met for the first time at this year's VMAs, which was not quite four months ago, and they've already made a song together.

Charlie and Sel teased a snippet of their new duet on Instagram December 10, and honestly, it seems pretty amazeballs. They previewed a Puth-penned song that shows off some acoustic guitar strummin' with a heavy, slow beat. #LoveIt

The new track seems to be called "We Don't Talk Anymore." That's not the case with Selena and Charlie, though. In th clip they seem to be having a blast with the song, as the Instagram clip shows the Revival singer dancing and wrapping her arm around new pal.

Don't worry, these two are just friends and working buddies. Selena was just caught getting her PDA with One Direction's Niall Horan last weekend, anyway.

"I have not only been following her career as a fan since I was 8 and now get to watch her completely transform in her new movie CAKE, I have gotten to have real conversations with such a real heart, made my entire year. #cake #goseeit"

"Never ended such a beautiful show in tears because they wouldn't allow me to Instagram tonight. Completely heart broken and pissed. Thank you SO much Brooklyn. Ill be stoping outside Letterman tomorrow to make it up if you can make it. I love you guys more than you know. Promise."
